3 Claims. 1

The invention relates to new and useful improvements in a heavy duty fiber container made from a single blank of fiber board which can be assembled for use without taping or stitching.

An object of the invention is to provide a heavy duty fiber container made from a single blank of fiber board which is cut and scored so that when assembled for use all of the various members constituting the container will be firmly locked in assembled position by the interengagement of parts of the container members.

A further object of the invention is to provide a heavy duty container of the above type wherein rigid reenforcing members disposed within the end members of the container extend from side to side of the container in the region directly above the hand holes in the end members.

A still further object of the invention is to provide a container of the above type wherein half-end members are formed integrally with the side members and wherein tabs fixed to the outer end members extend through slots in the halfend members for firmly locking the end members to the side members of the container.

A still further object of the invention is to provide the half-end members with extensions at their upper sides which fold over the rigid reenforcing members at each end of the container and onto-the inner face of the half-end members where they are locked by engagement with the tabs on the end members.

In the drawings, which Show by way of illustration one embodiment of the invention:

Figure 1 is a perspective view of a blank which is cut and scored so that the improved heavy duty container can be assembled therefrom, also showing in perspective the reenforcing members employed therewith;

Figure 2 is a View partly in perspective and partly in section showing the bottom side walls and the half-end members in assembled position and the outer end member partially folded to assembled position;

Figure 3 is a view similar to Figure 2, but showing the outer end member in assembled position and the reenforcing member in place preparatory to folding the extensions carried by the half-end members to final position;

Figure 4 is a view partly in vertical section and partly in side elevation of the container with the covers in closed position; and

Figure 5 is a sectional view on the line 5--5 of the container.

The improved heavy duty container is formed from a single blank of fiber board. The blank is cut and scored so that when assembled for use the container includes a bottom member having integrally connected thereto side and end members. The side members have formed integrally with the ends thereof, half-end members which fold into abutted position and form the inner wall of the end members, said halfend members are slotted close to the side members and tabs formed integral with the outer end members extend through the slots. These tabs have shoulders formed therein which are so positioned relative to the ends of the slots as to spring into engagement with the inner face of the end members and thus firmly secure the sides and end members in assembled position, said half-end members and outer end members having hand holes in register with each other and said half-end members having inwardly extending lugs in alignment with the upper side of the hand holes. A rigid reenforcing member, preferably of wood rests on said lugs and extends from side to side of the container. The end members have extensions which fold over the reenforcing member onto the inner face of the half end members where they are locked in assembled position by engagement with shoulders on the tabs. Cover members are formed integral with the side members and are dimensioned so as to rest on the end members when closed.

Referring more in detail to the drawings:

Figure 1 shows in perspective a single fiber blank. The blank is scored along the lines [-4 and 22 to offset a bottom for the container which is indicated at B in Figure 1. Extending along one side of the bottom is a side member S which is separated from the bottom by the score line I. There is a similar side member S at the other side of the bottom B separated therefrom by a score line I. At each end of the bottom member B are outer end members E which are separated from the bottom B by the score lines 2, 2. The side members S, S are folded along the score lines I, I to a vertical position in the assembling of the container.

Each side member at each end thereof is provided with an extension E. These extensions are separated from the side members by the score lines 3, 3. The half-end member E is separated from the end member E by a slit 4. There are four of these half-end members and when folded to assembled position the ends 5 thereof will lie in abutted relation as shown in Figures 2 and 3. Extending along the score line 3 centrally thereof is a slot 6, the purpose of which will be referred to later. These half-end members E are also out so as to provide portions 1 which may be folded inwardly to provide supporting lugs for a reenforcing member. The half-end member E is cut so as to provide a half hand hole 8. The half-end members are all similarly constructed and the reference numerals employed in the describing of one half-end member have been applied to the others.

Each end member is cut away to provide a hand hole 9. Projecting from the sides of the end member E. are tabs T. These tabs T are separated from the end members E by a score line H] so that the tabs may be readily foldedto a position at right angles to the inner face of the end member E. Each tab is provided with a notch forming a shoulder ll. Each tab at the lower end thereof is shaped so as to provide a locking lug l2.

After the sides S, S have been raised to a vertical position then these half-end members are folded inwardly along the score line 3 so as to form the inner wall of the end member of the container. These half-end members abut along the line 5 as noted above. The lugs 1,! are then folded to right angle position relative to the inner face of the half-end members. Placed on these lugs l, l is a reenforcing member 13. This reenforcing member is preferably made of wood and has some thickness and width so that when positioned on the lugs it provides a very rigid reenforcing member extending from one side of the container to the other as shown in Figure 3.

The end member E is formed integral with the bottom B and the slits forming the sides of the end member extend into the side members S, s as indicated at I l. This end member is now folded to .a vertical position and the tabs inserted through the slot 6. These tabs are so positioned that in order to pass through the slots the portion of the bottom along the slits i will yield downwardly to let the tab through the slot and then the whole end member will elastically spring back to its initial position and this causes the shoulders H to pass up along the inner face of the half-end members just above the slot 6. This makes a very firm locking engagement between the outer end member and the inner half end members which are integral with the side members.

Each half-end member E has an extension E which is separated from the half-end member E by placed score lines i5 and 16. This exten sion is provided with a half hand hole I! and also a recess it along the side of the extension. The half extensions E E are brought into abutted relation when the half-end members are folded to assembled position. This completes the hand hole I1.

The lugs I, i are so positioned thatthis reenforcing member 13 extends along the upper side of the hand hole 8 and upwardly to the score line !5 which is substantially the upper edge of the container. The extensions E are then folded downwardly so that the portion between the score lines 15 and [5 are in substantial contact with the upper side edge of the reenforcing member I 3.

The extensions are then folded downwardly along the score line It into engagement with the side wall of the reenforcing member H. The tabs extend through the recesses 18 in the extensions and the lugs l9 will move along the curved cam face of the lug l2 and spring into engagement with the inner face of the lug. This looks these extensions in assembled position. It also forms a substantial closed pocket within the end members for the reenforcing member [3.

At the upper edges of each side member is a cover member C separated from the side member by a score line 20. The cover hinges along this score line and will turn to a position for closing the container as shown in Figure 5. Extending along the free edge of the cover member C is a flap F. This flap is separated from the cover by a score line 2|. At the ends of the flap are extensions 22, 22 separated from the flap by a score line 23, 23. These extensions are also separated from the cover by a slit 24. The cover is so dimensioned that it overlies the reenforcing members l3 and the half-end members E These extensions 22, 22 fold inwardly as indicated in Figure 5 and will contact with the inner faces of the extensions E When the covers are swung to closed position these extensions contact the end wall and also contact each other as shown in Figure 5, and this serves to lock the cover sections in closed position.

From the above it will be noted that a heavy duty container is formed from a single blank of fiber board by cutting and slitting so that when assembled for use the parts are firmly held in assembled position by interlatching parts without the use of tape or any type of stitching devices. The hand holes are directly beneath the reenforcing member, and the end wall in the region of the hand holes consists of three plies which makes a very comfortable hand grip for the lifting and carrying of the container. The container is particularly adapted for the packaging of liquid products in bottles. When so used, the container, of course, will be provided with the usual transverse and longitudinal partitions dividing the container in the region of thebottom into cells, one for each bottle. These partitions, as noted, are of the usual construction and have not been illustrated in the drawings. 7
